| Error Message | Likely Cause | Fix | |---------------|--------------|-----| | “The type of upgrade file mismatches” | You are trying to upload the wrong firmware for your device model. | Double‑check the device model number and download the exact firmware from the official support site. | | “Language mismatch” | The firmware is designed for a different region (e.g. Chinese vs. International). | Obtain the firmware that matches your device’s region tag (CN, EN, OEM). | | Upgrade fails at 0% or stops at 5–10% | Network failure, incorrect FTP server IP, or the FTP service is not running. | Verify that the PC and device are on the same subnet, that the FTP server is actually running, and that the digicap.dav file is in the correct directory. | | “No enough space” or “File format error” | The firmware file is corrupted or the device’s flash memory is full. | Re‑download the firmware archive, extract it again, and ensure that no other operations are using the device’s storage. | | Device reboots in a loop after update | The upgrade was interrupted or the firmware is incompatible. | Use the TFTP recovery method to flash a known‑good firmware. | | SADP can see the device but cannot upgrade it | The device is in a degraded state but still responsive. | Use the web browser upgrade method (Configuration → System → System Maintenance → Upgrade) or try TFTP recovery as a last resort. | hikvision ftp firmware
. This is a specific recovery method used when a device's web interface is inaccessible. The Default IP Hook:
Disable the Windows firewall and any third-party antivirus software. These often block TFTP ports (UDP ports 69, 9978-9999). Turn off other network interfaces (Wi-Fi, VPNs) to prevent routing confusion.
Hikvision maintains official repositories where users can download the latest firmware files (typically named digicap.dav ). This is one of the most famous write-ups
Run your FTP server software. Copy the digicap.dav file into the directory that the server publishes. Make a note of your PC’s IP address.
The FTP user account assigned to the Hikvision devices must have read permissions to download firmware, and write/modify permissions if you also intend to use the server for event video storage or log archiving.
